Studies on the Structure and Diversity of the Ichthyofauna in the Coastal Insights into the Crustacea Decapoda of the Adriatic Sea. Observations from four sampling locations along the Croatian coast By Carsten H. G. Müller & Christoph D. Schubart MÜLLER C. H. G. & SCHUBART Ch. D. (2007): Insights into the Crustacea Decapoda of the Adriatic Sea. Observations from four sampling locations along the Croatian coast. Rostocker Meeresbiologische Beiträge 18: 112-130 Abstract. An annotated species list is provided on the basis of seven sampling surveys of decapod crustaceans carried out on various supra-, medio- and infralittoral substrates (sandy bottoms, rocky shores, seagrass beds of Posidonia oceanica) at four locations on the Adriatic Sea: Rovinj (in 1968), Slanik Bay (in 2001) and Pula (in 2004, 2005) on the Istrian Peninsula and the island of Šipan (in 2001, 2003, 2005) in the direct vicinity of Dubrovnik. All in all, 72 taxa were collected using shore sampling and snorkeling and scuba-diving techniques. The list of species collected is a good reflection of the spectrum of infralittoral Decapoda expected to be common along northern and southern Adriatic coastlines in the months of July and August. With a total number of 28 taxa (= 39%), the Brachyura represented the dominant group, followed by the Anomala with 20 species (= 28%) and the Caridea with (17 species = 24%). The majority of decapod crustaceans were captured on rocky substrates (51 taxa = 71%). Our present results provide an overview of typical infralittoral inhabitants within the studied areas. No Adriatic endemics and only one originally East Asian neozoan could be detected. No Lessepsian or Atlanto-tropical immigrants were encountered. Most decapod species collected have a wide distributionary range, including the whole Mediterranean Sea, or are constitutents of the Atlantic-boreal fauna in general. Besides confirming the occurrence of species reported by previous authors, we present new insights into the morphology, ecology, distribution and behaviour of some species. These are discussed in comparison to conspecific populations from other parts of the Mediterranean Sea. Kurzfassung. Eine kommentierte Artenliste von dekapoden Crustacea wird vorgelegt, entstanden durch Besammlung verschiedener Substrate des Supra-, Meso- and Infralittorals (Sand, Fels, Posidonia-Wiesen) an vier Plätzen des Adriatischen Meeres: Rovinj (1968), Slanik Bay ( 2001) und Pula auf Istrien (2004, 2005) und der Insel Šipan bei Dubrovnik (2001, 2003, 2005). Insgesamt wurden 72 Taxa nachgewiesen. Die Artenliste gibt das zu erwartende Spektrum der infralittoralen Decapoda wieder. Mit insgesamt 28 Taxa (= 39%), sind die Brachyura die dominierende Gruppe, gefolgt von den Anomala mit 20 Arten (= 28%) and den Caridea mit 17 Arten (= 24%). Die meisten Dekapoden wurden auf Felssubstrat gefunden (51 Taxa = 71%). Die Aufsammlung bietet einen Überblick über die typischen infralitoralen Bewohner im Untersuchungsgebiet. Keine adriatischen Endemiten und nur ein ursprünglich ostasiatisches Neozoon wurden nachgewiesen. Damit werden frühere Befunde bestätigt. Neue Mitteilungen betreffen Morphologie, Ökologie, Verbreitung und Verhalten für einige der vorgestellten Arten. Sie werden im Vergleich mit mediterranem Material von anderen Fundorten diskutiert. Key words: Crustacea, Decapoda, shallow water habitats, Adriatic Sea, zoogeography, ecology, biocoenoses 112 Introduction The Adriatic Sea is limited to the north by the lagoonary channel system around Venice and Trieste, while in the south it ends at the Strait of Otranto where the Adriatic Sea is connected to the Ionian Sea. Because of the high density of research facilities along its coastline, such as the classical marine biological institutes and museums in Venice, Rovinj and Dubrovnik, the Adriatic Sea is one of the best investigated biogeographic regions in the Mediterranean Sea. Many carcinologists have contributed to a long tradition of research, most of them especially interested in the Decapoda. The first documented insights into Adriatic decapod fauna were th presented at the beginning of the 16 century by GIOVIO (syn.: JOVIUS), whose first documented observations were made in 1524. ŠTEVČIĆ (1993) defined three distinct periods of significant carcinological research activity in the Adriatic Sea: the “post- Linnean-period” (1763-1846), the “Sinonimia-moderna-period” (1847-1968), and the “current-period” (1969-present). 124 species of the approximately 240 decapod species so far reported to inhabit the Adriatic Sea (see listings by PESTA 1918, RIEDL 1968, MANNING & ŠTEVČIĆ 1985, ŠTEVČIĆ 1990, 1991, 1995, 1998, 2002; D’UDECEM D’ACOZ 1999) were recorded in the “Sinonimia-moderna-period”. In the so-called “current period”, 51 species have been newly recorded for the Adriatic decapod community (ŠTEVČIĆ 1991, 1995, 1998, 2002, KIRINČIĆ 2003, 2006, SCHUBART 2003). Eleven species were newly recorded in the 1990s alone which is equivalent to an average rate of one to two species descriptions every year (ŠTEVČIĆ 2002). Several species are known to be endemic to the Adriatic Sea, which may underscore the independent faunistic role of this “Randmeer” in relation to western (Atlantic- Lusitanic) or eastern (Levante Basin, Red Sea) faunal elements and its importance for biogeography (cf. TÜRKAY 1989). The enormous progress in knowledge can surely be traced back to the no less than 70 contributions published in the relatively short period of almost 40 years (see ŠTEVČIĆ 1993, 2002). One possible explanation for the considerable increase of scientific activity during the “current period” may be a continuously growing interest in zoocoenotic questions. Obviously, a further reason lies in the necessity of documenting changes in the composition of Adriatic decapod fauna. Faunal and floral communities, more precisely in our case the infralittoral macrozoobenthos, must not be seen as static units. They are exposed to dynamic changes either caused by long- term climate shifts or produced by anthropogenic impacts. The marine macrozoobenthos, for instance, is influenced by the immigration or human-mediated import of allochthonous species from other biogeographical regions. Both processes are playing an increasingly important role in ecological research projects in the Mediterranean Sea. Many neobiota, among them many Decapoda, gained entry to Mediterranean littoral habitats in previous decades and established stable populations, partly by tending to invade neighbouring regions. A current and spectacular example is the Mediterranean spreading of the atlantico-tropical flat crab Percnon gibbesi (H. Milne Edwards, 1853), a highly mobile member of the Plagusiidae, which was recorded almost simultaneously on various islands in the western Mediterranean in the new millenium (e.g., Pelagie Islands (Isola di Pantelleria, Linosa): RELINI ET AL. 2000, PUCCIO ET AL. 2003, 2006, Balearic Islands: GARCIA & REVIRIEGO 2000, MÜLLER 2001, Sicily: PIPITONE ET AL. 2001, Greece: THESSALOU-LEGAKI ET AL. 2006, Turkey: YOKES & GALIL 2006). In total, six neozoic decapod species - the swimming crabs Callinectes danae Smith, 1869, Callinectes 113 sapidus Rathbun, 1896 and Dyspanopeus sayi (Smith, 1869), the brackish water- inhabiting panopeid crab Rhithropanopeus harrisii (Gould, 1841), the sea spider Maja goltziana d’Oliveira, 1888 and the penaeid shrimp Penaeus japonicus Bate, 1888 have been newly observed in the Adriatic Sea (D’UDECEM D’ACOZ 1999, ŠTEVČIĆ 2002). The first four of the species listed are known to stem from the northwest Atlantic, whereas M. goltziana comes from the tropical East Altlantic (see note of PALLAORO & DULČIĆ 2004). P. japonicus is originally an Indopacific species and should most probably be considered an escapee from local Adriatic aquacultures (see discussion in ŠTEVČIĆ 2002). It should be taken into account that the frequency and intensity of investigations into macrozoobenthic organisms has become much higher in the northern part of the Adriatic Sea, but that changes are most likely to occur first in the southern Adriatic Sea. We therefore believe that it will be useful to partially fill this gap by providing new observations concerning the community of Crustacea Decapoda populating various infralittoral substrates in the coastal waters around the island of Szipan, which have hitherto remained uninvestigated despited being located in the close vicinity of Dubrovnik in southern Croatia. We compared our collection of decapod crustaceans from Šipan/Jakljan with those collections that were carried out in three localities around Istria (northern Croatia). Going on the suggestions of ŠTEVČIĆ (2002), we particularly focused on hitherto neglected microhabitats such as seagrass beds of Posidonia oceanica, Cymodocea nodosa or Zostera spec. and primary hard bottoms of the upper infralittoral and mediolittoral zones respectively. Materials and methods During seven field trips to northern and southern sites of the Croatian coast in the years 1968, 2001, 2003, 2004, and 2005, various decapod crustaceans were collected through snorkelling and diving on sandy, muddy and rocky supra-, medio- and infralittoral bottoms down to 40 metres depth, according to the ecological zoning given by PÉRÈS (1967) and MARINOPOULOS (1988). The infralittoral zones investigated included habitats such as fields of rocky boulders (with or without macroalgae coverage), steep walls, seagrass beds, sac-shaped caves and grottoes. Samples were taken both during the day and at night, either by hand or by using hand nets. Sediments were sieved underwater with hand nets of a mesh

ORCID ID: http://orcid.org/0000-0002-1028-4356 Summary: A monitoring programme was established to collect plankton samples and information of environmental vari- ables over the shelf off the island of Gran Canaria during 2005 and 2006. It produced a detailed snapshot of the composi- tion and seasonal assemblages of the decapod larvae community in this locality, in the subtropical waters of the Canary Islands (NE Atlantic), where information about crustacean phenology has been poorly studied. The larval community was mainly composed of benthic taxa, but the contribution of pelagic taxa was also significant. Infraorders Anomura (33.4%) and Caridea (32.8%) accounted for more than half the total collected larvae. High diversity, relatively low larval abundance throughout the year and weak seasonality characterized the annual cycle. However, in relation to the temporal dynamics of temperature, two distinct larval assemblages (cold and warm) were identified that correspond to periods of mixing and strati- fication of the water column.

[email protected]; https://orcid.org/0000-0002-3479-2654 Abstract Morphological characters, as presently applied to describe members of the Paguristes tortugae Schmitt, 1933 species complex, appear to be of limited value in inferring phylogenetic relationships within the genus, and may have similarly misinformed understanding of relationships between members of this complex and those presently assigned to the related genera Areopaguristes Rahayu & McLaughlin, 2010 and Pseudopaguristes McLaughlin, 2002. Previously undocumented observations of similarities and differences in color patterns among populations additionally suggest genetic divergences within some species, or alternatively seem to support phylogenetic groupings of some species. In the present study, a Maximum Likelihood (ML) phylogenetic analysis was undertaken based on the H3, 12S mtDNA, and 16S mtDNA sequences of 148 individuals, primarily representatives of paguroid species from the western Atlantic. This molecular analysis supported a polyphyletic Diogenidae Ortmann, 1892, although incomplete taxonomic sampling among the genera of Diogenidae limits the utility of this finding for resolving family level relationships.

RICARDO CALADO, GISELA DIONÍSIO and MARIA TERESA DINIS CCMAR Universidade do Algarve, Campus de Gambelas, 8000-117 Faro, Portugal. E-mail: [email protected] SUMMARY: The present work identifies the decapod crustaceans that associate with Anemonia sulcata on the southwest­ ern Atlantic coast of Portugal and characterises their host use pattern. It determines whether the anemone is monopolised by any species, resulting in the exclusion of conspecifics or other decapods and, under laboratory conditions, it evaluates the degree of association between each species and A. sulcata. From all sampled anemones, 79% harboured at least 1 decapod crustacean, with the majority displaying either one or two specimens (32 and 24%, respectively). The most abundant species were the shrimp Periclimenes sagittifer and the crab Inachus phalangium (representing 36 and 31% of collected specimens, respectively), which displayed lasting associations and were commonly recorded among the tentacles of the host. The species Eualus occultus. complexE. cranchii. Clibanarius erythropus. Maja brachydactyla. Pilumnus and hirtellusPolybius (Necora) puber displayed short-term associations, were mainly present on the substratum near the base, and avoided the ten­ tacles of A. sulcata. Periclimenes sagittifer and I. phalangium were only recorded alone or in heterosexual pairs, appearing to efficiently defend their host against conspecifics. The majority of recorded species only seem to temporarily associate with A. sulcata, in order to seek protection from predators when other shelters are unavailable. Keywords'. Anemonia sulcata, associative behaviour, decapod crustaceans.

The observations that the South African population appeared suddenly and that it is located in and around a major international harbour, strongly suggest that it represents a recent shipping introduction. Porcellana africana was first detected at a single site within Saldanha Bay in 2012, but by 2016 was abundant under intertidal boulders and within beds of the invasive mussel Mytilus galloprovincialis across most of the Bay.

  • Decapoda, Xanthidae) in the Mediterranean Sea
    THE GENERA ATERGATIS,MICROCASSIOPE, MONODAEUS, PARACTEA, PARAGALENE,AND XANTHO (DECAPODA, XANTHIDAE) IN THE MEDITERRANEAN SEA BY MICHALIS MAVIDIS1'3), MICHAEL T?RKAY2) andATHANASIOS KOUKOURAS1) of Aristoteleio of ^Department of Zoology, School Biology, University Thessaloniki, GR-54124 Thessaloniki, Greece a. 2) Forschungsinstitut Senckenberg, Senckenberganlage 25, D-6000 Frankfurt M., Germany ABSTRACT A review of the relevant literature and a comparative study of adequate samples from the Mediterranean Sea and the Atlantic Ocean, revealed new key morphological features that facilitate a distinction of the Mediterranean species of Xanthidae. Based on this study, the Mediterranean Xantho granulicarpus Forest, 1953 is clearly distinguished from the Atlantic Xantho hydrophilus (Herbst, 1790) and Monodaeus guinotae Forest, 1976 is identical with Monodaeus couchii (Couch, 1851). For the species studied, additional information is given about their geographical distribution, as well as an identification key based on selected, constant features. ZUSAMMENFASSUNG Literaturstudien und vergleichende Untersuchungen geeigneter Proben aus dem Mittelmeer und dem Atlantischen Ozean haben neuen morphologische Schl?sselmerkmale erbrqacht, die eine Un terscheidung der aus dem Mittelmeer stmmenden Arten der Xanthidae erleichtern. Als Ergebnis dieser Untersuchungen kann gesagt werden, dass Xantho granulicarpus Forest, 1953 aus dem Mit telmeer klar von Xantho hydrophilus (Herbst, 1790) aus dem Atlantik unterschieden ist und dass Monodaeus guinotae Forest, 1976

Signature: ……………………………………………………… 2 PRICE Abstract In nature, one of the most common and effective adaptions for reducing the threat of predation is to decrease the likelihood of detection through camou- flage. The shore crab (Carcinus maenas) faces several predators in the wild and is also widely distributed across several habitats differing in substrate. Previous literature has recorded the diversity in shore crab pattern particularly amongst juveniles, linking the variation in pattern to differences in habitat sub- strate. A possible explanation for these phenotype - environment associations, is morphological pattern change. However, the plasticity of pattern variation in shore crabs has received little attention. Building on previous studies’ findings, that the shore crab is capable of changing brightness, for the first time, this study assesses whether shore crabs are also capable of changing carapace pattern under experimental conditions, to improve camouflage over a period of 12 weeks on two artificial backgrounds. My findings show that indeed, shore crabs show plasticity in carapace pattern and brightness, and that, through the eyes of avian and fish vision, this resulted in improved camouflage for individu- als on the uniform artificial background.
